【T*ash Mob Reincarnation】Since I Gained an “Ero Doujin” Ability in a Wholesome Game, I Decided to Steal All the Heroines from the Scumbag Protagonist

This protagonist is such a s*umbag, I can’t leave the heroines to him. I’ll take them all myself. Before I knew it, I was inside the romance game I’d mastered in my previous life. It’s an all-ages romance simulation, but when I woke up, I’d somehow gained a ridiculous skill called “Ero Doujin.” Once you get a power that lets you do this and that with the game heroines you’ve always admired, there’s no choice but to go for it, right? I wanted the girls to be happy, but the protagonist is such a jerk that a bad end is inevitable, so I decided to take them all and make them happy myself.
